چکیده انگلیسی
Polarization complex-plane plot of impedance for two-stage anodic reaction with partial charge transfer, complicated with an intermediate adsorption, is theoretically analyzed. The case of linear coverage dependence of the oxidation rate and linear potential dependence of the effective number of electrons involved in each stage, hence, quadratic potential dependence of the activation energies is considered. The result of the modeling agrees qualitatively with experimental data on benzene oxidation at boron-doped diamond electrode. The using of the partial charge transfer concept allowed revealing fine effects of the organics oxidation, which are ascribed to adsorption, in particular, emergence of a loop in the polarization complex-plane plot of impedance.
